Introducing the SpeedBlocks Head Immobilizer. Designed for durability and performance, but priced for disposability, SpeedBlocks really gives you the best of both worlds. SpeedBlocks offer a simple, four-step process for application, a unique, multi-axis blocks system to accommodate all head shapes and injury positions and direct access to patient's ears for better communication and inspection. The low-cost blocks with disposable foam pads and head straps are so effective that the inconvenience of taping the patient can be eliminated.
